I. Preparing the motherboard

• Install standoffs in MB

for updates.

Swiftech assumes no liability whatsoever, expressed or implied, for the use of these

The following instructions are subject to change without notice. Please visit our web site at

You must uninstall your MB prior to installing the
MCW478-UT water-block.
Remove the stock heatsink support base (the black
plastic frame that clips down to your motherboard).

Standoff

Nylon, hex nut

on back side of

the MB

This will reveal the four mounting holes we use to
install our standoffs. Install a standoff in each one of
the holes. Keep the standoff centered over the MB
holes, and secure with nylon hex nuts on backside of
the MB. If you are going to assemble/disassemble the
heat sink frequently, we recommend finishing the
installation by putting a drop of “Crazy Glue “ at the
junction between standoff & MB, and between nylon
hex nut & MB. This will lock the standoff onto the MB,
and further prevent it from spinning lose during
frequent assembly and disassembly operations.

• Fill-up the socket with dielectric grease. Do not confuse

dielectric grease with thermal compound. Dielectric grease
is used to prevent condensation where parts are exposed
to cold. We recommend Luberex (available on our web
site under the accessories section), or any similar product,
with good dielectric properties. Fill-up the socket center
cavity (grease is to be level with the upper surface of the
socket), and coat the socket pinholes with grease. Spread
the grease with your finger so that it will penetrate inside
the pinholes.

• Remove the peel-off paper back from the motherboard

gasket, and install it as shown Figure 2. The sticky side
should be towards the motherboard.

• Insert the processor into the socket. Since you have

grease inside the socket, some hydraulic pressure lift may
occur: for this reason, make sure that the processor sits
perfectly flat, and is inserted all the way into the socket.
Then, coat the processor core with high quality thermal
compound. Only a paper-thin coat is necessary. It
should be applied using preferably a razor blade, or a
credit card, held between thumb and index at a 45-degree

•

To further prevent condensation to occur behind the motherboard, a neoprene sticker is provided with your water-block accessories.
Apply it to the back of the motherboard, behind the processor.

• Re-install the MB inside the case.

II. Water-block installation

• IMPORTANT WARNING:

the wires of the thermoelectric module are
extremely fragile. Bending the wires at their
root will systematically break the solder joint,
and the thermoelectric module cannot be
repaired. For this reason, we route the wires
inside the holes of the brackets that are
normally used to mount socket 423 or Xeon
processors. If you need to use these mounting
holes for your Xeon or socket 423 Pentium 4,
you should first disassemble the brackets, very
carefully re-route the wires in the socket 478
mounting holes, then re-install the brackets.

Swiftech will not honor the warranty for broken
wires.

• It is preferable to insert the tubing into your

MCW478-UT water-block prior to installing it
onto the CPU. The reason is that inserting the

tubes into the fittings requires some strength,
and it is preferable not to do this while the block
is sitting on the CPU. If you are going to use
soft vinyl tubing (transparent tubing), it is
IMPERATIVE that you use the two plastic
inserts provided with your kit.

• Orientation of the block is important for

bleeding purposes. Please look-up the
critical bleeding instructions paragraph on
page 3 prior to installing the block onto the
CPU.

Install the water-bl;ock assembly onto your processor, as shown
on figure 3. Gradually tighten the screws in a crisscross pattern

until you feel that they reach the bottom of the standoff. A “finger­tight” lock is sufficient. Over tightening may result in stripping the
nylon hex nut. Conversely, adjustments such as tightening the
screws only partially are strictly prohibited
in improper contact between the CPU core and the heat sink, and
result in CPU overheating.

Due to wide variations in gasket thickness tolerances, we
suggest that you uninstall the water-block once, following the
initial assembly just to verify that you have good contact
between the cold plate and the CPU. Inspect the grease imprint
that the CPU left on the copper plate: it should be perfectly
even!
